why social network analysis
Why Social Network Analysis?
  • Understanding dynamics of information flow
  • Identifying important actors
  • Leveraging the best out of existing network
    • Faster and efficient information diffusion
    • Greater control over data flow
we are looking for
We are looking for….
  • Pollinators: Stars of the network
    • Not necessarily the most popular
    • A good pollinator has more number of pollinators down stream
    • Many ways of identifying critical actors
  • Bridges: Important connections.
    • May not have a diverse sub-network, but connect to other critical actors
parameters for pollinators
Parameters for Pollinators
  • Number of outward connections: measured using the metric, out-degree.
  • Diversity:
    • A measure of the degree to which the actor can spread the data.
    • Measured using the betweenness centrality.
  • No of prominent actors downstream
    • Measured by eigen vector centrality
  • Depth: Depth is defined here to signify how much distance (in terms of degrees of separation) the information can flow thru an actor.
    • The smaller the closeness centrality the more isolated(or distant) from the network, the actor is.
    • Can be measured by the negative value of the closeness centrality of the most distant actor in the network.
  • Density: Dense network in one city
